Mangroves Initiative - Green and Grey Infrastructures in the Philippines
Published on
Implementation of Green and Grey Infrastructures
In the Philippines, the project covers 4 sites in Iloilo province: Bagongon, Loong, Bacjawan Norte, and Tambaliza. At each site, several structures have been installed, combining soft solutions (mainly bamboo structures) and grey solutions (small stone dikes) to trap sediment and/or reduce wave action prior to reforestation.
Green solutions: a 9-metre-long structure for wave attenuation and another 895 metres long for sediment trapping were installed at the Bagongon site (see map below, sites 1, 3, 4, 6, 8).

COVID slowed down most of these activities.
Development of alternative activities in the demonstration sites
Value chain analysis workshops were held in August 2018 with partner community organizations. Business plans for each of the identified livelihoods were also prepared with the community to help partner organizations focus on their specific identities, target markets, and products or services.
Coconut is one of the most important crops in the Philippines, with the country being the second largest coconut producer in the world, and the identified activities are essentially based on this production.
| Site | Proposed Activities | Progress |
| Barangay | Production based on coconut fibres (Geonets) Virgin coconut oil production |
Production site set up, equipment provided, training delivered Equipment provided, training delivered |
| Tambaliza | Vegetable farming | Production of 259 kg of vegetables (profit of 12,618.00 PhP) |
| Loong | Local chicken production | Pending the end of Covid |
| Polopiiia | Clothing manufacturing | Training in school uniform manufacturing (schools closed due to Covid) |
| Bacjawan Norte | Vegetable and poultry farm | Pending the end of Covid |
Promotion of green-grey solutions : The various events, training workshops, and local, national, and international meetings on “green-grey” solutions were all cancelled due to Covid.
